xcb_map_window_checked3
Makes a window visible
Part of xcb_map_window(3).
Usage
Request function
xcb_void_cookie_t xcb_map_window(xcb_connection_t
*conn,
xcb_window_t
window);
Request arguments
- conn
-
The XCB connection to X11.
- window
-
The window to make visible.
Overview
Maps the specified window. This means making the window visible (as long as its parent is visible).
This MapWindow request will be translated to a MapRequest request if a window manager is running. The window manager then decides to either map the window or not. Set the override-redirect window attribute to true if you want to bypass this mechanism.
If the window manager decides to map the window (or if no window manager is running), a MapNotify event is generated.
If the window becomes viewable and no earlier contents for it are remembered, the X server tiles the window with its background. If the window's background is undefined, the existing screen contents are not altered, and the X server generates zero or more Expose events.
If the window type is InputOutput, an Expose event will be generated when the window becomes visible. The normal response to an Expose event should be to repaint the window.
Return value
Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.
If you want to handle errors directly with xcb_request_check instead, use xcb_map_window_checked. See xcb-requests(3) for details.
Errors
- xcb_match_error_t
-
The specified window does not exist.
